Chemistry 104: Analysis of an Antacid Tablet. A sample of an antacid tablet was analyzed by the following procedure, to determine how many moles of simulated stomach acid (0.131 M HCl) it would neutralize. A 0.19 g sample of an antacid tablet was placed in an Erlenmeyer flask containing 20.00 mL of 0.131 M HCl.

Overview. Antacids are over-the-counter medications that help neutralize stomach acid. They work differently from other acid reducers such as H2-receptor blockers or proton pump inhibitors, which work by reducing or preventing the secretion of stomach acid. Antacids usually come as a liquid, chewable gummy or tablet,

indirect method or what is known as a back titration. The antacid is allowed to react with a known amount of hydrochloric acid and then the excess hydrochloric acid is titrated with sodium hydroxide. The amount of acid reacted or neutralized by the antacid is determined by difference. moles neutralized = moles initial – moles excess

Instead a back titration of base with excess acid will be employed. Why? CO2 gas is released during the chemical reaction and is a slow step. There is a time delay between the addition of the acid and the completion of the reaction. The endpoint of the titration would be unclear because straight titration does not allow enough reaction time.
